lNSlDE BLIND FOR wmoows.

SPECIFICATION forming part of Letters Patent No. 393,052, dated November20,1888.

Application filed April 30 1888. Serial No. 272,351.

To all whom it may concern;

Be it known that 1, CHARLES H. AMEs, a citizen of the United States,residing at Delta, in the county of Fulton'and State of Ohio, haveinvented certain new and useful Improvements in Inside Blinds forWindows; and I do hereby declare that the following is a full, clear,and exact description of the invention, which will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form part of this specification.

My invention relates to inside blinds for windows-such as are usuallyaffixed to the inside casing of the window in sections of two ormore-and has for its object to construct each section with anadaptability to be folded against the inside casing to afford anunobstructed view, or with slats so journaled in the hinged sectionsthat they can be turned to at ford a partial view or entirely close theblind.

Another object is to arrange the slats vertically and secure the same inthe metal frame by pivots formed in the end of the slat by having thematerial removed concentrically from the solid portion of the center ofthe slat.

Another object is to construct the upper and lower portions of the frameof metal parts hinged together, with each metal part provided with oneor more hollow bosses, into which the slat is secured.

In the drawings, Figure l is an elevation of a window provided withinside blinds composed of four sections, the upper half being shownclosed, one lower section folded, and the remaining section partiallyfolded. Fig. 2 is a top plan view of a section of blind partiallyfolded. Fig. 3 is an elevation of a section of blind, showing the upperframe composed of metal bars joined by a tongue and groove joint, theview being drawn with the section partly folded. Fig. 4 is a plan viewof a portion of one section of blind partially folded, with the slatspartially opened. Fig. 5 is an edge and Fig. 6 is a side View ofaportion of the metal frame, showing a modified form of hinge and thehollow bosses in which the slats are pivoted. Fig. 7 is an elevation ofone end of a slat, showing the pivot formed therein.

(No model.)

Fig. 8 is an elevation of a preferred form of bit for forming the pivotupon the slat.

A designates the window,to which are hinged upper sections, B and O, andlower sections, D and E, of inside blinds constructed in accordance withmy invention. Each section comprises a side bar, F, hinged to thewindowcasing, and E, which forms the opposite side, connected at top andbottom by a series of metal bars or stiles, G, hinged together at Geitherby a tongue-and-groovejoint,asshown in Fig. 3, or a lap-hinge,asshown in Fig. 5, or by any preferred construction of hinge, so thatthe bars are capable of being folded upon each other, as shown at theright in Fig. 2. Each metal bar G is formed with one or more cylindricalbosses, G, havinga circumferential perforation extending in depth to thethickness of the boss, and preferably terminating in conical shape, intowhich is inserted acylindrical pivot, H,of slat H, the outer end of thepivot being preferably of conical shape, by which means the slats extendperpendicularly and have a rotative moment in the metal bars. To theinner edge and about midway the length of the slats is secured aflexible tape, J, by which the slats may be moved at right angles to thebars to admit light and permit observation through the window or beclosed when desired.

To open the blinds When closed, the hinged bars are folded upon eachother, as shown at the right in Fig. 2, or,' if it is desired to admitlight to the room with the sections of blinds closed, tape J is pulled,thereby giving each slat a partial rotation upon its pivot, and theslats are brought with their width at right angles to the bars.

By forming the pivots H in the body of the slat, whereby the material ofwhich the slat is composed surrounds the piv'ot'concentrically, there isa much more finished appearance given to the blind than when the pivotextends beyond the length of the slat, the pivot being also more easilyformed by means of a hollow bit, as shown in Fig.8,when j ournaledin afixed arbor.

The metal bars may be cast or stamped of any suitable material,andfinished by grinding and polishing, or by plating, if desired.

The metal bars and slats may be constructed as an article ofmanufacture, and any desired number of the same purchased from stock, itbeing simply necessary to unite a sufficient number of bars to measurethe width of the window, and needing no skilled labor to as- 5 semblethe parts and form ablind.

What I claim,and desire to secure by Letters Patent, is-

1. The herein-described inside blind, consisting of longitudinal barsand transverse [0 bars composed of metal sections hinged together andprovided with circular bosses having concentric recesses for thereception of slat: pivots, in combination with slats formed with pivotsand having a body portion concentric 15 therewith, as and for thepurpose set forth.

2. In a slat-frame for an inside blind, end bars consisting of sectionsformed of metal hinged together and provided with projecting own Ihereby affix my signaturcin presence of 0 two witnesses.
